Write the expression for the de Broglie wavelength associated with a charged particle of charge q and mass m, when it is accelerated through a potential V.

Text Solution

Verified by Experts

The correct Answer is:
`K.E. = (1)/( 2) mv^(2) = eV; v= sqrt((2eV)/(m))`
v - speed of the electron
`lambda = ( h )/( mv ) = ( h )/( sqrt( 2qmV ))`
